nxPANDnD-METAL CHAPLET.

Specification of Letters Patent.

To all whom it mag/concern:

Be it known that I, PERCY HAIGHT BAT- 'rEN, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have made and invent ed certain new and useful Improvements in Expanded-Metal Chaplets, of which'the following is a specifica-tion.

My invention relates to the manufactur of'brake shoes having an insert embedded i the body portion thereof, said insert being commonly made of metal, such as hard steel or wrought iron, the object thereof being'to provide means for holding the metallic 1nsert in placein a metal mold, While molten metal is poured thereinto land about the 1nsert, whereby the same finally becomes embedded in the cast metal body portion of the shoe. l

More specilically stated, the object of my invention is to provide a chaplet for holding.

the metallic insert in place in a met-al mold, said chaplet comprising a foraminous member, formed preferably from expanded metal and adapted to engage the insert, and to extend to and contact with an adjacent wall of the metal mold, to thereby hold the in-y sert in place and prevent it from becoming displaced or from slipping' upon the surface of the mold during the process of casting.l

With the above and other objects in view, my invention consists in the improved chaplet for holding metallic inserts in place hereinafter described and illustrated in the accompanying drawing, and in such variations and modifications thereof as will be obvious to those skilled in the art to which my invention relates.

In the accompanying drawing wherein the preferred embodiment of my invention is illustrated, Figure 1 is a view showing a part of the lower portion of a metal mold in plan, the view illustrating one type of insert and one form of chaplet for holding the same in place. Fig. 2 is a similar view showing another type of insert and a second form of chaplet. Fig. 3 is 'a view showing a section upon a plane indicated by the line 2--2, Fig. 1; and, Fig. 4 is a view illustrating a section upon a plane indicated by theline 3-3, Fig. 2.

Referring to the drawing, the reference meral 4 designates a part of the'lower part of a metal mold in which brake shoes are cast, it being understood that the complete I mold also includes an upper or cope portion, (not shown) and that the two parts of the.

mold inclosea cavity in the form ofthe article to be cast.

The reference character 5 designates ametallic insert, continuous throughout its length, and 6\ designates a plurality of metallic inserts, the shoe formed inl the'lirst case having a single insert, while in the second case the same has a plurality of separate and `distinct inserts. i

Referring first to the form of my invention adapted for holding the single insert 5 .in place, the same comprises two foraminous .members 7, located one at either end of the insert, and in engagement therewith, which foraminous members extend to and contact with the inner walls of the recess 8. These members 7 are preferably pressed, or otherwise given the form shown in Fig. 3, that' is they are formed with recesses so as to fit over the ends of the insert, thereby providing a shoulder at 9, the end of the forarninous member being turned up as shown at 10, these features insuring a secure or firm hold upon the end of the insert and the -wall of the recess 8, and preventing the chaplet lfrom displacement as the shoe is formed.

The chaplet is preferably formed from expanded metal, and it will be understood is, together with the metallic insert 5, embedded in the' brake shoe as the same is formed.

In case the brake shoe is to be provided with a plurality of metallic inserts 6, my improved chaplet takes the form of a foraminous member extending the entire length of the recess in the mold in which the shoe is formed. Such a chaplet is shown in Figs. 2 and 4 and comprises a foraminous member 11 formed preferably from expanded metal, and which member is Iprovided with a series 'of pockets made by cutting the chaplet and forcing the edges downward as shown at 12,

Awhereby a series of pockets are produced in forced into the mold to thereby more firmly hold the same and the inserts in place. In this form of my device the metallic inserts are firmly held in pockets formed in the foraminous member as above explained, the peripher tending eyond the inserts. and into engagement with the inner Walls of the mold.

The chaplet, in both forms of my device, is preferably foraminous in, order that the fluid metal as it is poured into the mold may iiow about the chaplet as Well as about the metallic insert, both becoming embedded in the shoe as the same is cast.

'Having thus described and explained my invention, I claim and desire to secure by Letters `Patent 1. A foraminous member adapted to eli-A lgage an insert to be embedded, 1n the cast metal body portion of an article as the same is formed, and to engage also an inner adjacent Wall of the mold 1n which said article is cast, to thereby form a chaplet for holding the insert in place during the casting operation.

v 2. A chaplet forholdng a metallic insert in position within a metal mold, the same comprising a foraminous member in engagement with said insert and which member extends to and engages the inner surface Vof the mold.

3. The combination with an insert to be embedded in a cast metal article as the same is formed, of a. foraminous member in enlgagement with said insert and extending eyond the same a distance suiiicient to of the foraminous member exengage the inner surface of the mold in which the article is formed.

4. A chaplety for holding a metallic insert of a brake shoe in osition within a metal moldas Huid meta from which the shoe is formed is poured thereinto, the same comprising a foraminous member formed from expanded metal and which member engages said insert and extends toand contacts with the inner surface of the mold.

5. A chaplet for holding a metallic insert of a brake shoe in position within a metal mold as uid metal from which the shoe is formed is poured7 thereinto, the same comprising a foraminous member formed from expanded metal and having a recess 1n which said lnsert 1s contained, and which member extends beyond said inserta distance suiicient to engage the inner surface of the mold in which the shoe is formed.

6. The combination with a metallic insert to be embedded in a cast metal brake shoe as the same is formed in a metal mold, of a foraminous member formed from expanded metal and having a recess in which `said insert is contained and which member extends beyond said insert a distance suficient to engage the inner surface of the mold in which the shoe is formed.
